Abstract

We have studied the size-dependent optical scattering of aqueous suspensions containing Mg₂Al-LDH platelets, which exhibit high total- and side-scatterings. By incorporating 3 wt% Mg₂Al-LDH platelets (280 nm) in a commercial sunscreen formulation, we achieved a twofold Sun Protection Factor boost, providing a promising, high-efficient and non-toxic strategy to enhance sunscreen effectiveness.
